Yoga is IT undergraduate, requiring him to face computer on prolonged hours most of the days. He finds that his eyes are tired easily, seeing blurry near vision sometimes. With complaint of blurry near vision or tired eyes with digital devices in children or young adult, we will look into & check two main components of our eyes, Accommodation and Vergence.
Given the complaint at the beginning of eye examination, we will have in mind the certain eye assessment that we want to perform in order to find out the cause of your complaint.
From the result of assessments, we know that Yoga:
1. Vergence is fine
2. Accommodation is fatigued
– that tallies with his complaint.. considering the amount of hours spent in front of computer.
Due to increased of near work in this era, there are 3 ways to go about this:
- Manual way: we manually relax our eyes/eye muscles by 20-20-20 rule, after every 20 minutes of seeing near, to look at 20feet away for 20seconds
- With help of lenses: instead of us manually relax our eyes, we use spectacles lens to help relax our eyes let Relax lenses help support to do the auto-focusing, instead of our eyes do all the auto-focusing work for us, so eyes are more relax – especially for those with excessive near work
- To strengthen eye itself by vision therapy (according to your eye disorder – Accommodation / Convergence / Binocular Disorder etc)
Our management for Yoga is:
- we prescribe Relax lens to help support his Accommodation due to his excessive near work, an option chosen by him too
- wear new power for 4-6weeks & to come back for follow up on his near complaints & his PRA
- to strengthen/improve his accommodation/focusing ability by vision therapy
- reinforce proper visual hygiene: SARANGHAE – applicable for everyone too
Happy to hear that the glasses “it’s great”, Yoga?
Thank you Yoga for your trust & support!?
